    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 i+M*J#'  
    F}ukZ DB  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: B!aK  
    enableservice('AutomationServer', true) L~FTr  
    enableservice('AutomationServer') #w3ru6*W  
    6*1$8G`$8,  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 OKwOugi0

    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 7S2C/f  
    1. 在FRED脚本编辑界面找到参考. |9NIGg'n  
    2. 找到Matlab Automation Server Type Library DOL%'k?B  
    3. 将名字改为MLAPP -4L!k'uR  
    =L 0fZf  
    (N U0T w  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 5A_4\YpDR

    1. 创建Matlab服务器。 (M% ;~y\  
    2. 移动探测面对于前一聚焦面的位置。 c>Z*/>~  
    3. 在探测面追迹光线 @oH[SWx  
    4. 在探测面计算照度 kN'Thq/ZE  
    5. 使用PutWorkspaceData发送照度数据到Matlab z<a2cQ?XQ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Da,&+fZI!  
    7. 用Matlab画出照度数据 0P 5BArJ?  
    8. 在Matlab计算照度平均值 S=R 3"~p
